Bone tissues are hard and rigid due to the presence of calcium salts and collagen fibers, providing support and structure to the skeleton. Bone tissues are highly vascularized, allowing for the delivery of nutrients and removal of waste products to ensure bone health and repair. Bone tissues have the capacity to grow, adapt, and heal through processes such as remodeling and mineralization.
While most of the body is made of water, and the skeleton (bones) contain calcium carbonate, proteins make up the rest of the body tissues and also are also active chemically in the cells.
The tissues that make up their bodies decays and falls apart. If it is a hard coral, then a calcium carbonate skeleton is left behind.
The skeleton is made up of bones.
The axial skeleton is the bones that make up the centre or core of the skeleton to which the appendicular skeleton which bones attach to.
Specialized cells make up specialized tissues. The tissues make up an organ, but organs use different tissues.
